Testing recovery data input. The 80A07 recovers a full-rate clock up to 12.5 Gb/s, an important requirement for testing XFP and other 10 Gb/s MSA modules.
Getting Started Key Features The 80A07 provides a quality clock recovery solution with the following features: H 100 Mb/s to 12.5 Gb/s continuous data rate coverage H Accurate variable loop bandwidth from 100 kHz to 12 MHz H Auto lock capability with LED display...
Getting Started Installation To install the 80A07, connect the supplied AC power cord to a properly grounded AC supply. The input voltage requirement is 100 VAC to 240 VAC at 50 Hz to 60 Hz. Press the power button on the instrument using the front-panel On/Standby switch.
To prevent damage to the instrument, do not apply a signal outside the Maximum Input Voltage Swing.

Getting Started CAUTION. To prevent electrostatic damage to the 80A07 and other instrumenta- tion, follow the precautions described in this manual and in the documentation provided with any connecting instruments. (See Electrostatic Discharge starting on page 3.) NOTE. For best repeatability and to prolong connector life, use a torque wrench, and tighten the connection to the range of 79-112 N⋅cm (7-10 in lb).

Reports whether the CR is locked, unlocked, or in the process of locking. By default, the 80A07 is configured in Auto Lock Mode, where it automatically attempts to acquire lock if the detected Phase Error exceeds the Phase Error Limit setting or if the recovered clock is unstable. The user may force a relock at any time by pressing the Lock button.
Remote Control Remote control of the 80A07 is possible with the use of the Software Develop- er’s Kit (SDK). The SDK is available on the CDROM provided with your instrument. Refer to the instructions provided on the CDROM for use of the developer’s kit.

The Jitter Transfer Function is not exactly an inverse of the PLL loop frequency response. The slope of the jitter transfer function, as well as its peaking will often be different that of the PLL loop response. 80A07 Clock Recovery User Manual...

PLL response. Several examples of the jitter transfer function versus PLL loop response can be seen in the next section. The 80A07 has the ability to measure the PLL response and the jitter transfer function and display a plot of these to the user. This can be useful to understand the relationship of these parameters at the particular data rate.
Page 27
80A07 requires information on the edge density to keep the loop parameter settings calibrated. In the 80A07, this can be done by one of two methods, auto and manual modes. In auto mode, the actual average edge density is measured and automatically calibrates the loop parameter settings.
However, full control of parameters is possible with direct entry of the user parameters. The 80A07 has variable jitter peaking, allowing jitter gain in excess of 10 dB if desired.
